30V 3.6W LED Controller Steady On Mode, JT-DC300V0120-C Class 2 Power Supply Transformer, Low Voltage Transformer US Plug for LED Light (30V 0.12A)

This worked great and it was nice to have all ornaments lit up.

Pulled my Christmas tree down from the attic to discover the lights didn’t work. Checked the power supply with a meter and it was only putting out 12V instead of the rated 30V. Waited it with this one and it’s good as new!

Item was exactly what we needed. For and function was perfect.

My display went dark just a couple of days before Halloween, messed with all the wires looking for a short and found nothing. I thought I would take a chance on a new transformer and searched by the model number on Amazon. Low and behold they had it in stock and it came the next day too. I installed the new transformer and the crew came back to life. I did notice in small print on the transformer it states to keep the transformer a foot above the ground even though it claims it’s weather sealed. I think I’ll follow this precaution in the future. Thanks Amazon!!

Exact replacement, works great.

Power supply was what I was looking for, works great

Why did I not think of this before wasting hundreds and thousands of dollars on Christmas trees?! This transformer was a life saver. Tree was decorated but the lights did not work! Instead of changing the entire Christmas tree or wrapping lights around it, just change out the transformer. Perfect.

This is another data point where this transformer only lights every other LED on my light string. I purchased to replace a transformer with several functions but no memory.
